resemble it in habit and the soil which it affects, a su- 
periority will be found, which ranks this as one of the 
most valuable grasses; . next to the Poa angustifolia , it 
produces the greatest abundance of early foliage, of the 
best quality, which fully compensates for the comparative 
lateness of flowering.

The strong nutritive powers which this grass possesses 
recommend it to the notice of occupiers of strong clayey 
lands which cannot be drained. Its produce is great, 
and the foliage will not be denominated coarse, if compared, 
with those which afford, a produce equal in quantity.

If the weight which is lost by the produce of this sped#! 
of clover, in drying, be compared witli that of many of tile 
natural grasses, its inferior value for the purpose of hay 
compared to its value for green food, or pasture, wgi 
appear; for it is certain that the difficulty of rnakino- good 
hay increases in proportion with the quantity of superflu- 
ous moisture which the grass may contain. Its value for 
green food, or pasture, may further be seen by comparing 
its nutritive powers, with those manifested by other plantl 
generally esteemed best for this purpose.
